Abstract

Dieselpartikelfilter zur Absenkung der Emission von im Abgas eines Dieselmotors enthaltenen Partikeln, dadurch gekennzeichnet, daß die bezüglich des Abgasstromes bei einem Betrieb des Dieselmotors anströmseitige Oberfläche des Dieselpartikelfilters (1) derart ausgebildet ist, daß sich eine Adhäsion von nicht verbrennbaren Aschepartikeln (4) an dieser Oberfläche des Dieselpartikelfilters (1) allenfalls nur mit solchen Bindungskräften einstellt, daß die Aschepartikel (4) mit einem Fluid und/oder durch Schwingungseinwirkung von dieser Oberfläche des Dieselpartikelfilters (1) entfernbar sind.
